Recently I've been getting random blue screens. I'm beginning to think it is my hard drive. They happen every two weeks usually but now they've been happening more then usual. They usually happen when I'm on my desktop or browsing with chrome. I've checked all my temps and all of them are safe. I haven't noticed any strange noises from the hard drive nor have I experienced any sluggish peformance.

First thing you want to do is put everything back on stock to see if the error still occurs (maybe even test for stability while you're at it) which would include your CPU, GPU, and RAM. Another thing would be to remove any add-on (optional) items either from your expansions slots or anything connected via externally. If the errors stops popping up then you can reconnect anything one by one to see if a certain hardware is causing the problem. It's really tough to determine if a hard drive would be the culprit since I've never experienced a drive causing a BSOD...however I understand that it may be possible...which I'm guessing may be a defective drive PCB. I do hope you find out your problem since troubleshooting is such a pain and lengthy process.

Grab Defraggler, check the Health tab for your drive, and then post a screenshot for us here.

Most dying drives display something bad in their SMART data - but not always.

That said, I just fixed some BSODs for someone by resetting their CMOS and setting up the BIOS again. Same settings, but it wasn't stable before and it is now. Temps can be great, but sometimes issues are caused by the strangest things - don't rule anything out without first testing it.

Hmm... that's peculiar. Your drive isn't failing in any typical way. Usually when they start to go, Reallocated Event Count, Current Pending Sector, etc. begin increasing. but yours are all at 0 in the "Real Value" column.

That said, some of the other attributes aren't perfect, so I can't rule failure out. I have quite a few WD Green drives - most have spinup times in the 5000-6000ms range.

UDMA CRC Error Count usually indicates a bad SATA cable (replace the cable and it stops increasing), but it could also indicate a bad SATA controller. (either on your motherboard or HDD PCB) I'd replace your SATA cable and swap ports, if possible.

Multi-Zone Error Rate is the worrisome one. I only ever had that on one WD Green - it shot up a few weeks before the drive died. But that drive also had tons of Reallocated Event Count and Current Pending Sector, so I don't know for certain.

It might be easier to rule out your other hardware instead. I would say you should run a stability test in the background for a while, and see what it reports. Maybe test your memory too.http://www.ocbase.com/http://www.memtest.org/
